Bicycle set-up dimensions and cycling kinematic data are important components of bicycle fitting and cyclist testing protocols. However, there are no guidelines on how bicycles should be measured and how kinematic data should be collected to increase the reliability of outcomes. This article proposes a consensus regarding bicycle set-up dimensions and recommendations for collecting cycling-related kinematic data. Four core members recruited panellists, prepared the document to review in each round for panellists, analysed the scores and comments of the expert panellists, reported the decisions and communicated with panellists. Fourteen experts with experience in research involving cycling kinematics and/or bicycle fitting agreed to participate as panellists. An initial list of 17 statements was proposed, rated using a five-point Likert scale and commented on by panellists in three rounds of anonymous surveys following a Delphi procedure. The consensus was agreed upon when more than 80% of the panellists scored the statement with values of 4 and 5 (moderately and strongly agree) with an interquartile range of less than or equal to 1. A consensus was achieved for eight statements addressing bicycle set-up dimensions (e.g. saddle height, saddle setback, etc.) and nine statements for cycling kinematic assessment (e.g. kinematic method, two-dimensional methodology, etc.). This consensus statement provides a list of recommendations about how bicycle set-up dimensions should be measured and the best practices for collecting cycling kinematic data. These recommendations should improve the transparency, reproducibility, standardisation and interpretation of bicycle measurements and cycling kinematic data for researchers, bicycle fitters and cycling related practitioners.

自行车设置尺寸和骑行运动学数据是自行车配件和骑行者测试协议的重要组成部分。但是，没有关于如何测量自行车以及如何收集运动学数据以提高结果可靠性的指南。本文就自行车设置尺寸提出了共识，并提出了收集骑行相关运动学数据的建议。四名核心成员招募了专家组成员，准备了每轮供专家组成员审查的文件，分析了专家组成员的分数和评论，报告了决定并与专家组成员进行了沟通。14 位具有自行车运动学和/或自行车配件研究经验的专家同意作为小组成员参加。提出了 17 个陈述的初步清单，使用五点李克特量表进行评分，并由小组成员按照 Delphi 程序在三轮匿名调查中发表评论。当超过 80% 的小组成员对值为 4 和 5（中等和强烈同意）且四分位间距小于或等于 1 的陈述进行评分时，达成了共识。针对自行车设置维度（例如鞍座高度、鞍座后退等）的 8 项陈述和针对自行车运动学评估的 9 项陈述（例如运动学方法、二维方法等）达成了共识。本共识声明提供了有关如何测量自行车设置尺寸以及收集骑行运动学数据的最佳实践的建议列表。这些建议应为研究人员、自行车装配工和骑行相关从业者提高自行车测量和骑行运动学数据的透明度、可重复性、标准化和解释。
